`foo()' should return fred and bob.  The alternative would be to use
global variabels which is seldom a good idea.

So you get:

def foo(seq):
    '''foo -- makes foo of sequence'''
    output = []
    bob = 32768
    fred = ['a', 6, 'yo mama', 'c']
    return fred, bob

def test():
    f, b = foo([])
    f.append(1)
    return f
